BOILER FEEDING AND CLEANING ATTACHMEN'I.

SPECIFICATION forming part of Letters Patent No. 692,073, dated January28, 1902 Application filed July 24, 1901. Serial No. 69,522. (No model.)

To all whom it may concern: 5

Be it known that I, CHRISTIAN REISER, a citizen of the United States,residing at Lake Charles, in the parish of Oalcasieu and State ofLouisiana, haveinvented certain new and useful Improvements in BoilerFeeding and Cleaning Attachments, of which the following is aspecification;

Thisinvention relates to steam-boilers, and has special reference tomeans forsupplying the same with feedwater and at the same time makingprovision for removing the scales, sediment, or mud in order to preventthe accumulation thereof within the working parts of the boiler.

To this end the invention primarily contemplates an improved feeding andcleaning attachment for steam boilers comprising means for deliveringthe feed-water into the same and also embodying an improved arrangementof parts to insure the deposit of all solid matter, sediment, and thelike within the area of the feeding devices and also providing for thecomplete blowing out or removal of such matter While the boileris inuse, hot, and under working pressure, thereby permitting the boiler tobe run continuously for anylength of time and cleaned out at any time.

With these and many other objects in view,

which will more readily appear as the nature of the invention is betterunderstood, the same consists in the novel construction, combination,and arrangement of parts hereinafter more fully described, illustrated,and claimed.

The fundamental features of the invention are necessarily susceptible toa wide range of modification; but a preferred embodiment is shown in theaccompanying drawings, in

whiching the arrangement of dams and cleaning' devices associatedtherewith. Fig. 3 is a sectional view on the line 3 3 of Fig.1,indicatingin dotted lines the relation of such pans to the manhole inwhich is fitted the manhead carrying all of the connections for thefeeding and cleaning devices.

Like numerals of reference designate corre-' sponding parts in theseveral figures of the drawings.

' In carrying out the invention the same may necessarily be associatedwith different types of boilers, it only being necessary that the attachment be arranged within the live-steam space of the boiler so as tobe exposed to the steam-pressure; but as the attachment pos sessesspecial utility in connection with a water-tube boiler the same isillustrated in the drawings as associated with a boiler of this type.

The invention embodies in its general organization a' plurality ofelongated feedingpans, through which the feed-water is delivered intothe boiler, and in the preferable construction a pair of these pans areused, as shown in the drawings, said pans being designated,respectively, by the numerals l and 2. In the construction illustratedin the drawings the feeding pans 1 and 2 are arranged in superposedrelation one above the other and are inclined in opposite directions, sothat the feed-water must run the entire length of both pans beforefinding an outlet or escape into the boiler from the discharging end ofthe lower pan. 1

The upper and lower feeding-pans 1 and 2 may be of any desiredconstruction, but are necessarily of a trough-like form in order toprovide a chute through which the feed-water maybe circulated, and byreason of being oppositely inclined the said pans necessarily convergetoward one end, at which end they are suitably united, and acirculating-opening 3 is provided at the extreme lower end of the upperpan 1 to provide direct communication between the two pans, so that thefeedwater may flow from the upper pan into the higher end of the lowerpan.

The two pans 1 and Z are open at the upper side throughout their entirelength, so that the feed-water passing therethrough is exposed directlyto the pressure of the live steam within the boiler, and in using theinvention, as shown in the drawings, the said pans 1 and 2 are designedto be supported inside of the live-steam space or drum 4 of a boiler 5and viating the caking thereof.

may be conveniently supported in position by suitable supporting-legs 6or the like fitted to the bottom pan 2 and resting on the boilerfiues.

The upper feeding-pan 1 has suitably fitted to the higher end thereof aninlet-valve casing 7, opening directly into the pan 1, andin which isarranged an upwardly-openingcheckvalve 8. To the inlet-valve casing 7 isalso coupleda feed-water pipe 9, extending the interior of the boilerand passing through a stuffing-box 10 in a manhead ll, suitably fittedin a manhole 12, provided in the end of the boiler. A valved blow-outpipe 13 also passes through a stuffing-box 14, carried by the manhead11, and is connected at its inner end within the boiler to the lower endof the pan 2, so as to communicate with the blowout hole 15. Above theplane of the said blowout hole 15 the end wall at the lower end of thepan 2 is cut away to providea water-outlet opening 16, through which thefeed-water overflows into the boiler.

Each of the feeding-pans is provided with a series of paralleltransversely-arranged fixed dams 17 in the form of short plates arisingfrom the bottom of the pan and extending transversely across the bottomfrom side to side thereof. A series of these parallel dams or dam-plates17 range from end to end of each pan,and alternating with the fixeddam-plates of each pan are a series of scraper-blades 18, carried by areciprocatory cleaning-frame 19. The {cleaning-frame 19 within each panpreferably consists of an open rectangular framework having parallelside bars 20, to which are secured the pendent scraper-bladesl8,and byreason of said scraper-blades projecting from the under side of theframe carrying the same the said blades have a play within the spacebetween the fixed upstanding damplates. The reciprocating frame 19Within each feeding-pan has an operating-rod con nection 21 therewith.This operating-rodextends through the manhead ll and may have connectedtherewith exterior to the boiler a suit-able lever, whereby thecleaning-frame may be reciprocated wherever it is desired to loosen upthe sediment for the purpose of blowing the same out through theblow-out pipe 13.

In the operation of the boiler and the attachment therein the fixed dams17 cause the feed-water to be spread thereover in thin sheets, thusallowing the full action of the head of steam upon the feed-water, andall solid matter is caused to be deposited in the pockets between thedams, the different kinds of solid matter being separated sufficientlyto make the depositsin the pans soft and ob- By opening the valve in theblow-out pipe 13 and. reciprocating the cleaning-frames to loosen up andput in circulation the mud and other sediment the latter will beentirely cleaned out of the pans and blown off under the steam pressurethrough the pipe 13.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described boiler feeding and cleaningattachment will be readily understood by those skilled in the artwithout further description, and it will also be understood that variouschanges in the form, proportion, and minor details of construction maybe resorted to without departing from the spirit or sacrificing any ofthe ad vantages of the invention.

'Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A boiler attachment of the class described, comprising a pair ofupper and lower feeding-pans in communication with each other andinclined in opposite directions, the upper pan being provided with aninlet-valve casing having an upwardly-opening check- Valve, and thelower of said pans being provided at its lower end with a blow-out holeand above the plane of said hole with an overflowopening, afeed-water-pipe connection with the said inlet-valve casing, and ablowout-pipe connection with said blow-out hole.

2. A boiler attachment of the class described, having a feeding-pan forthe feedwater provided with a succession of upstanding fixed dam-platesprojecting from the bottom thereof, and a cleaning device having pendentmembers working in the spaces between said dams.

3. In a boiler attachment of the class described, a pan forthefeed-Water provided at the bottom thereof with aseries of spacedupstanding short flat dam-plates, a reciprocating frame arranged withinthe frame and having a series of depending fiat blades working withinthe intervals between the dam projections, and exterior operating meansfor said frame.

4. In a boiler attachment of the class described, the combination of theboiler having in one end a manhole fitted with a detachable manhead, apair of oppositely-inclined communicating feeding-pans supported withinthe steam-space in line with said manhole, a feed-waterv pipe extendedthrough the manhead and connected with the upper pan, a bloW-outpipealso extending through the same manhead and connected with the lowerpan, and reciprocatory cleaning devices arranged within both pans andhaving exterior operating-stems also extending through the said manhead.

In testimony whereof I affix my signature in presence of two witnesses.

CHRISTIAN REISER.
